A digital object identifier (DOI) can be used to cite and link to electronic documents.
A DOI is guaranteed never to change, so you can use it to link permanently to electronic
documents.

To find a document using a DOI
1. Copy the DOI of the document you want to open.
The correct format for citing a DOI is as follows: doi:10.2298/JSC0702159L
2. Open the following DOI site in your browser: http://dx.doi.org
3. Enter the entire DOI citation in the text box provided, and then click Go.
The document that matches the DOI citation will display in your browser window.
The DOI scheme is administered by the International DOI Foundation.
Many of the world's leading publishers have come together to build a DOI-based document linking scheme known as CrossRef.
